My RV had a serial number list printed out on a sticker placed in the bedroom closetMy wife promptly ripped off said sticker the 1st night not knowing what it was, but I saved the pieces form the trash and took a picture for future reference. Maybe you have such a list on a sticker or in your owners manual....listed models and serial numbers for all the major stuff.... fridge, furnace, ac, etc...

My awning was affected by that recall. Supposedly mine was repaired before it left the factory???
